I used this as an alternative to the Oxford type heated grip. These elements stick onto the handle bars and you can use any grip you like. They came with a switch. wiring etc. They have a high and low setting but are so hot on the high setting that I've only used them on ther low setting so far.
They came from the states and delivery was excellent.
